Description
- The present invention relates to a clinch bolt for fixing by crimping and coupling, by inserting a screw shaft part into a mounting hole pierced in a metal plate, and pressing a head part to the metal plate.
- For example, a
clinch bolt 1 is hitherto known as shown inFig. 11 and Fig. 12 , in which crimpingprotuberances 5 are provided on aseat surface 4 of ahead part 3, an annular ridge part 6 of a larger diameter than the outside diameter of ascrew shaft part 2 is formed in an under-neck portion immediately beneath theseat surface 4, and anannular groove 7 is formed between the annular ridge part 6 and theseat surface 4, and more specifically thescrew shaft part 2 is inserted into amounting hole 11 slightly larger than the outside diameter of the annular ridge part 6 pierced into ametal plate 10, thehead part 3 is pressed to themetal plate 10, the crimpingprotuberances 5 are press-fitted into theperipheral edge 12 of themounting hole 11, and theperipheral edge 12 is crimped and deformed to bite into theannular groove 7, so as to be fixed tightly to themetal plate 10. - Since the
mounting hole 11 pierced in themetal plate 10 for fixing theclinch bolt 1 has a slightly larger diameter than the annular ridge part 6, when thescrew shaft part 2 is inserted into themounting hole 11, and the crimpingprotuberances 5 protruding from theseat surface 4 of thehead part 3 are positioned to abut against themetal plate 10, a considerable dimensional difference exists between theinner periphery 11a of themounting hole 11 and thewall 7a of theannular groove 7. Hence, in particular, when the metal plate is thin, as shown in the drawing, a misalignment may occur between themounting hole 11 in themetal plate 10 and theannular groove 7 of theclinch bolt 1. If thehead part 3 is pressed, crimped and coupled into themetal plate 10 in such misaligned state, the deformation amount of theperipheral edge 12 of themounting hole 11 biting into theannular groove 7 by crimping and deforming is not uniform, and the clinching force may be insufficient. -
US-5,797,175-A discloses a clinch bolt having the features of the pre-characterizing portion ofclaim 1. - Thus, there is a need for a clinch bolt capable of obtaining a stable clinching force, without occurrence of misalignment between the mounting hole in the metal plate and the annular groove of the clinch bolt.
- The present invention provides a clinch bolt having crimping protuberances formed on a seat surface of a head part, having an annular ridge part of a larger diameter than the outside diameter of a screw shaft part and formed on an under-neck portion immediately beneath the seat surface, and having an annular groove formed between the annular ridge part and the seat surface, for inserting the screw shaft part into a mounting hole slightly larger than the outside diameter of the annular ridge part and pierced into a metal plate, pressing the head part to the metal plate, press-fitting the crimping protuberances into the peripheral sedge of the mounting hole, and crimping and deforming the peripheral edge to bite into the annular groove, so as to be fixed tightly to the metal plate, characterized in that at least three misalignment preventive protuberances projecting from the wall of the annular groove in the radial direction are disposed at intervals in the circumferential direction, and the distal ends of the misalignment preventive protuberances are disposed on a virtual circumference of nearly same diameter as (or slightly greater diameter than) the diameter of the annular ridge part.
- To prevent the inner periphery of the mounting hole from being engaged with the annular groove, preferably the lateral sectional shape of the misalignment preventive protuberances is formed in a pointed triangular or pentagonal shape, or in a narrow trapezoidal or rectangular shape. At least three protuberances are needed, and up to five may be preferred in order to prevent the inner periphery of the mounting hole from being engaged with the annular groove.
- Preferably, the outer edges of the misalignment preventive protuberances are formed in a taper shape which widens in the upward direction from the outer periphery of the annular ridge part toward the seat surface, and when the screw shaft part is inserted into the mounting hole until the seat surface of the head part is closer to the metal plate, the tapered outer edges of the misalignment preventive protuberances contact with the inner periphery of the mounting hole, and are aligned by the automatic centering action, and misalignment can be effectively prevented.
- As explained herein, according to the present invention, in a simple configuration having at least three misalignment preventive protuberances projecting from the wall of the annular groove in the radial direction formed between the annular ridge part provided in the under-neck portion immediately beneath the seat surface of the head part and the seat surface, it is effective to prevent securely misalignment between the mounting hole in the metal plate and the annular groove, and therefore a stable clinching force is obtained.

-
Fig. 1 to Fig. 3 show the clinch bolt of the present invention. The basic configuration of theclinch bolt 21 is common to theconventional clinch bolt 1 shown inFig. 11 and Fig. 12 , that is, crimpingprotuberances 25 are projecting like a lattice from aseat surface 24 of ahead part 23 consecutively provided at the upper end of ascrew shaft part 22, and eachcrimping protuberance 25 is gradually increased in thickness from the inside to the outside of theseat surface 24. In the under-neck portion immediately beneath theseat surface 24, anannular ridge part 26 of a larger diameter than the outside diameter of thescrew shaft part 22 is projecting, and anannular groove 27 is formed between theannular ridge part 26 and theseat surface 24, and so far the configuration is same as in the prior art, except that three misalignmentpreventive protuberances 28 projecting in the radial direction are provided in awall surface 27a of theannular groove 27 at equal intervals in the circumferential direction. - The misalignment
preventive protuberances 28 are more specifically shown inFig. 3 , in which the lateral sectional shape is a pointed triangular shape, and the leading end is disposed on a virtual circumference having a nearly same diameter as the diameter of theannular ridge part 26. -
Fig. 4 to Fig. 7 show the crimping process of fixing theclinch bolt 21 having such configuration to themetal plate 10 by crimping and coupling, in which themetal plate 10 is preliminarily provided with amounting hole 11 slightly larger than the outside diameter of theannular ridge part 26. This point is same as shown inFig. 11 . -
Fig. 4 and Fig. 5 show the preparatory step before the crimping process, in which thescrew shaft part 22 is inserted into themounting hole 11, and theseat surface 24 of thehead part 23 is brought closer to themetal plate 10, and eachcrimping protuberance 25 is in a positioning state abutting against themetal plate 10. At this time, as explicitly shown inFig. 5 , the leading ends of the three misalignmentpreventive protuberances 28 are engaged with theinner periphery 11a of themounting hole 11, and they are positioned almost concentrically in a state of preventing misalignment between themounting hole 11 and theannular groove 27. Moreover, since the lateral sectional shape of the misalignmentpreventive protuberances 28 is formed in a pointed triangular shape, when thescrew shaft part 22 is inserted in themounting hole 11, theinner periphery 11a of themounting hole 11 is not prevented from being engaged with theannular groove 27. If the number of the misalignmentpreventive protuberances 28 is too many, theinner periphery 11a of themounting hole 11 may be prevented from being engaged with theannular groove 27, and hence the number of the misalignmentpreventive protuberances 28 is not more than five.Fig. 4 shows the location of ablanking die 15 for use in a next crimping process. -
Fig. 6 and Fig. 7 show the crimping process of theclinch bolt 21, in which thehead part 23 is pressed to themetal plate 10, and in cooperation with an annular projectingpart 16 of theblanking die 15 shown inFig. 4 , thecrimping protuberances 25 projecting from theseat surface 24 and the annular projectingpart 16 of theblanking die 15 are pressed to theperipheral edge 12 of themounting hole 11, and theperipheral edge 12 is crimped and deformed to bite into theannular groove 27, and is crimped and coupled to the under-neck portion immediately beneath thehead part 23 by a stable clinching force, so that theclinch bolt 21 is fixed to themetal plate 10. At this time, an annular recess groove 13 is formed in theperipheral edge 12 by the annular projectingpart 16 of theblanking die 15. -
Fig. 8 shows other preferred embodiment of the misalignmentpreventive protuberances 28, in which (a) shows the lateral sectional shape formed in a pointed pentagonal shape, and (b) and (c) show the inner periphery of themounting hole 11 formed in a lateral sectional shape of a narrow trapezoidal or rectangular shape so as not to interfere engagement with theannular groove 27. -
Fig. 9 and Fig. 10 show another preferred embodiment. In this preferred embodiment, the lateral sectional shape of the misalignmentpreventive protuberances 28 is pointed same as in the foregoing preferred embodiment, but theirouter edges 29 are formed in a taper shape spreading widely toward theseat surface 24. In such configuration, when theseat surface 24 of thehead part 23 is brought closer to themetal plate 10 by inserting thescrew shaft part 22 into themounting hole 11 of themetal plate 10, before thecrimping protuberances 25 abut against themetal plate 10, as shown in the drawing, the taperedouter edges 29 of the misalignmentpreventive protuberances 28 contact with theinner periphery 11a of themounting hole 11, and thescrew shaft part 22 is aligned concentrically with themounting hole 11 by the self-centering action, so that misalignment between themounting hole 11 and theannular groove 27 can be securely prevented, and a more stable clinching force is obtained.
